dc.description.abstractThe volcanic activity of Mt. Karacada? (SE Anatolia) is divided into three major stages: Siverek Stage (?11-2.7Ma), Karacada? Stage (?1.9-1.0Ma) and Ovaba? Stage (0.4-0.01Ma). The magmas are mildly alkaline mafic rocks, mostly basanites, hawaiites and alkali basalts. Detailed geochemical investigation indicates a continuous variation of composition with time, with the oldest products (Siverek Stage) being characterized by average lowest HFSE (Ti, Hf, Zr, Nb, Ta), 143Nd/ 144Nd, Nb/U, Ta/Yb, Nb/Nb <sup/> and the highest ?Q, La/Nb, Ti/Nb, Zr/Nb, Ba/Nb, Th/Ta, K/La, and the youngest products (Ovaba? Stage) at the opposite end of the trend. The overall incompatible element content of the Karacada? volcanic rocks resembles closely average HIMU-OIB compositions, with the oldest samples deviating more strongly from typical compositions of "anorogenic" magmas. We interpret these geochemical variations with a process of partial melting of a chemically and mineralogically heterogeneous mantle source rather than with process of variable crustal contamination at shallow depths. During the first stages of mantle melting the volumes with lowest solidus temperature (e.g., the amphibole and phlogopite-rich metasomes, particularly abundant in the Arabia mantle xenolith suite) contributed significantly to the partial melts. "Average" peridotitic matrix is involved in partial melting processes only when these metasomatic volumes start to be exhausted, producing mantle melts with geochemical composition resembling average "anorogenic" mildly alkaline sodic rocks, common in the circum-Mediterranean area.en_US

dc.description.sponsorshipWe thank the local people for their warm welcome during the fieldwork. Bob Stern (Dallas, USA) is thanked for the help in collecting Arabian Plate lower crustal xenolith data. Samuele Agostini (Pisa, Italy), Brian G.J. Upton (Edinburgh, UK) and an anonymous referee provided constructive reviews that helped to improve the quality of the manuscript. Raffaello Trigila (Rome) is thanked for designing and assembling the equipment to produce the glassy beads. ML thanks, as usual, his three women Enrica, Bianca and Laura for their immense patience during the writing of this manuscript. ML also thanks Rick Wakeman, Bill Bruford, Steve Howe, Jon Anderson and Chris Squire for being so “fragile”. MK thanks the Istanbul University Research Fund (project # ACIP-1282) for their support during the fieldwork in 2007. This work was supported by a joint project TUBITAK-RFBR (TUBITAK Project # 108Y222, Turkey and RFBR project # 09-05-91220-CT) between 2009 and 2010, by research grants from University La Sapienza (AST 2008, 2009) and from PRIN 2008 (Research Grant#: 2008HMHYFP_005). O.K. thanks M. Sefik İmamoğlu for a discussion on field geology.en_US
